PRINTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 323,925, dated August 11, 1885.

Application filed October 31. 1&3. (No model.)

i" 0 all whom it may concern.-

Be it known that I, HENRY P. FEIsTnR, of the city of Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented an Improvement in Printing Machines, of which the following is a specification.

My invention has reference to printing-machines; and it consists in certain improve ments upon Letters Patent granted to me November 7, 1882, and numbered 267,172. In that patent the sheet which is carried by one impressioncylinder, after being printed upon one side, is transferred ,to another impressioncylinder, being reversed by the operation, and is printed upon the other, the transferring of the sheet from one cylinder to the other being effected by means of currents of air and nippers upon said cylinders. In this improvement I dispense with the use of air, and employ in lieu thereof a transfer-frame secured to one of said cylinders and operating to throw the lower edge of the sheet over against the second impression-cylinder at the proper moment, which sheet is then caught by the nip-' pers on said second cylinder and carried around to receive the second impression, as fully set forth in the following specification, and shown in the accompanying drawings, which form part thereof.

In the drawings, Figure 1 is a side elevation of a printing-machine embodying my invention. Fig. 2 is an enlarged sectional elevation of a portion of the two impressioncylinders in the act of transferring the sheet from one to the other. Fig. 3 is a front elevation of a part of the impression-cylinder provided with the transfer-frame, and Fig. 4 is a sectional view of the end of one of the adjustingscrews for the cams which actuate the nippers and transfer-frames.

A is the frame of the machine, and may be 'provided with a track or guideway, A, upon which the endless bed of carriages 13 runs, which carriages support the type-forms.

O and D are the two impression-cylindcrs, and have impression-faces c and d, which are adapted to print from every alternate typecarriage, those which are omitted by cylinder D being printed from by cylinder 0. There may be any desired number of impression-sun faces upon these impression-cylinders. Each impression-surface is provided at the advance end with nippers H, which are secured to a shaft, it, provided with a pinion, H, which meshes with a segmental gear, K, secured to a shaft, k, to the end of which is secured a crank, K, which may be normally kept in one direction by a spring, These nippers H are operated through the above mechanism by cams N, L, R, and R, which are pivoted to the axis of the cylinders O and D, and may be adjusted by screws S, which pass through nuts T, pivoted to the frame A, the ends of said screws S being grooved, as at s, and received in the ends of socket-pieces S, which are pivoted to the cams, being retained within said socket-piece by a screw or pin, 8, and allowed to rotate freely therein.

Any other form of adj usting mechanism may be used in lieu of that just described.

E is the roll of paper, F F are the measuring rolls or cylinders, and G is the knife, which parts may be made substantially as shown in said patent of mine hereinbefore referred to, and also Letters Patent granted to me April 18, 1882, A and numbered 256,662. Theseimpression-cylinders O and D and carriages B may be synchronously driven by means of gearing shown in said patents.

U are the inking-rollers, and are preferably located between said impression-cylinders,

and U is a screen or shed to prevent the paper held by the impression-cylinders accidentally coming in contact with the said inkingrolls.

P are the transfer-frames, and consist of armsP, slotted at their bottoms, as; at p", and are secured at their tops to rock-shafts p, carrying on their ends cranks O,Which are drawn in one direction by springs 0. NVorking on the bottoms ofsaid arms P are the cross-bars P, which are secured thereto by screws P. The bottoms of these plates or bars P are notched, as at p, to allow the nippers to pass when clamping the bottom of the paper in the act of transferring. The arm P may be setin a recess, D in the periphery of the cylinder D, and in the center thereof, so as to rest between the two impression-surfaces, which correspond to two pages, it being preferable to print two-page sheets from each carriage B.

If single-page sheets are to be printed, then ICO upon the margins of the sheet, so as not in any manner to interfere with aperl'ect impression.

M is a shield to prevent the sheets falling away from the cylinder D. B are the delivery-tapes. I) istheiiy-frame. b is the receiv ing-table, and L the folding and trimming mechanism, all these devices being clearly shown in Patent No. 256,662, hereinbefore referred to.

The operation is as follows: The paper E is fed between rollers or cylinders F and cut off by cutter G into sheets of thereqnired size. The nippers H on cylinderD areheld open by cam L, and as the crank K runs over the end thereof the said nippers close suddenly upon the end of the sheet and carry it forward. After being printed upon by the type-forms on carriages B it ascends, and the cam Q, acting on crank O, swings out the transfer-frame 1, thus throwing the bottom edge of the sheet X over within reach of the nippers H on the cylinder 0, which have been kept open by cam 1t, and which suddenly close upon the said pa per. At the same instant the cam N opens the nippers H on the cylinder 1), so as to allow the sheet to be carried oit' by cylinder 0, and having been reversed it is printed upon the other side by the type-forms on one of the carriages l3 omitted by the cylinder D. The cam It then opens the nippers H, and the sheet, printed upon both sides, is carried off to the folding apparatus.

The cams L, N, Q, R, and B may be accurately adjusted by the screw S, so as to actuate the nippers and transfer-frames at exactly the proper instant to insure the proper manipulation of the sheets.

Vhile I prefer the construction shown,I do not limit myself to the details thereof, as they may be modified in various ways without dcparting from my invention.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

1.. In a printing-machine, two impression cylinders provided each with one or more impression 'surfaces, in combination with a series of type-forms arranged to be passed in succession in contact with said cylinders, one of which cylinders prints from alternate typei'orms, and the other of which prints from those omitted, nippers arranged upon said cylinders, mechanism, substantially as described, to operate said nippers to catch and deliver the sheets, transier-frames, substantially as described, pivoted to one of said cylinders and adapted to swing thetail end of the sheet over to the other cylinder, where it is caught by the nippers before the sheet has left the first impressioncylinder, and mechanism, substantially as described, to operate said transferframes at the proper instant, substantially as and for the purpose specified.

2.
